public class ConcludesBatchParameterResolverFactory
extends AbstractAnnotatedParameterResolverFactory<ConcludesBatch,Boolean>
implements ParameterResolver<Boolean>

Parameter resolver factory for boolean event handler parameters annotated with ConcludesBatch. If the event is processed in the context of a BatchingUnitOfWork and is the last of the batch the resolver injects a value of true. If the event is processed in another unit of work it is always assumed to be the last of a batch.
